Hi there. Yes, Pain in the groin, radiating to the inside of the thigh and sometimes the knee is usually classical for hip problems like arthritis. Avoid squatting, cross leg sitting. Mild hip muscle strengthening exercises can be done. Do not over exercise beyond your comfort zone. Try to be fit and avoid obesity which can make hip arthritis worse. Eat healthy. Keep well hydrated. You may need to see your Orthopaedician because he will grade your level of arthritis and let you know if you can manage on just medication and lifestyle changes or need a hip replacement.
